| ILLUMINATED SWITCHES TP1251: ILLUMINATED PUSHBUTTON SWITCHES FEATURES * * * * * * * * Momentary switch action 12mm square Very low profile High brilliance illumination 3 LED colour options Suitable for membrane backlighting Standard 2.54mm terminal pitch High reliability due to simplified operating mechanism and low current DESCRIPTION The TP 1251 series of miniature, PCB mounted, pushbutton switches is designed for applications that demand a minimal overall height and are particularly suitable for illuminated membrane switch panels. The switches are fully backlit and are available in red, yellow and green and exhibit a high degree of brilliance due to an innovative filter and reflector construction. A simplified operating mechanism and low current requirement ensure high reliability in use.
